Question
Transcribed Image Text:A block of mass m is on top of a block of mass M = 3m. The two blocks are connected by a string that passes over an ideal pulley. The bottom block is also tied to a string - exerting a force F, after
the blocks have been set in motion, causes the blocks to move at constant velocity.
m
F
Use g = 10 N/kg for this problem. The coefficient of kinetic friction between all surfaces in contact is 0.300.
